Mathematical Meditations

Snezana Lawrence is a mathematical historian and mathematics educator, and has been working in higher education for the past 15 years. Prior to that, Snezana was a teacher and teacher trainer in the English school-system. She was a lead consultant for the Prince’s Teaching Institute for Mathematics 2009-2018. Currently Snezana works as a Senior Lecturer in the Department of Mathematics and Design Engineering at Middlesex University, London, teaching mathematics, mathematics history, and risk.Snezana’s plan for the next few years it to write more popular history of mathematics books and to work more with teachers and people interested in identifying their local history of mathematics in libraries and museums where they live, across Europe. She was the Chair of the History and Pedagogy of Mathematics International Study Group for 2020-2024.

"Throughout the book, a reader is encouraged to step away from the text to think, write, or draw; to me, these opportunities will mean one reader will experience a slightly different book than another. Each chapter ends with 'Further Investigations,' which often include book recommendations, so the total time you can spend with this title is quite open-ended. It is clearly written for both mathematicians and aspiring mathematicians, as it is stripped of technical components and prerequisites. I expect that high school teachers, undergraduates, and liberal arts students would enjoy this book, along with anyone who agrees that “math is life.” I certainly appreciated the way Mathematical Meditations invited my mind to travel down various pathways of open-ended mathematical imagination."-AMS Notices
